As the Prime Minister lands in Algiers I'm left wondering: Is it more about diplomatic logic than existential threat?
David Cameron warned that north Africa is becoming a "magnet for jihadists" as he announced help to tackle the terror threat in the region.
A British man from Aberdeenshire has spoken to ITV News about his dramatic escape from militants and his concern for some of his colleagues.
Tributes have poured in for David Morgan, the British teacher who is understood to have been killed when the Air Algerie flight crashed in Mali.
PE teacher Andy Vasily posted tweeted: "RIP Dave Morgan. Truly tragic. Prayers to his family and other victims."
Former @nischina teacher killed in Algerian plane crash. RIP Dave Morgan. Truly tragic. Prayers to his family and other victims.
He added that Mr Morgan had previously worked at Nanjing International School in eastern China.
Others including Hanri de Swardt from South Africa, paid their respects on Facebook.
De Swardt, a fellow teacher, wrote: "Rest in peace Captain Dave Masher Morgan. Thanks for all the support and help in Lusaka. You will always be in my thoughts. God bless."
She added: "Remember the nice evening at Brentwood with all our last food before leaving Zambia."
Another teacher Annabelle Mambwe from the Luanda International School, in Angola, wrote: "Just lost a teacher colleague in the Algiers disaster. Dave Morgan!! He was Denise's Maths teacher...such an easy-go-fella! These planes falling from the sky are getting to me!"
A British man killed when an Air Algerie flight crashed in northern Mali is understood to be David Morgan, ITV News has learnt.
Prime Minister David Cameron earlier said he was "deeply saddened" by the death of the British national.
At least 118 people died in the disaster, with nearly half of those aboard the flight believed to be French nationals.
French government officials have revised the death toll of the Air Algerie plane crash to 118, without explaining the reason for the change.
They also raised the number of French killed from 51 to 54.
Aerial footage of the site where Flight AH5017 crashed was also released by regional military authorities this evening.
Prime Minister David Cameron said he was "deeply saddened" by the death of a British man on the Air Algerie flight AH5107.
"Thoughts very much with friends and family," he added.
Mr Cameron has also written to Mr Hollande "to send sincere condolences for the loss of so many French citizens", Downing Street said.
A strong smell of aircraft fuel and the fact that debris was scattered over a small area suggests the Air Algerie plane crash was linked to weather or a technical problem, French Transport Minister Frederic Cuvillier has said.
Aviation officials lost contact of flight AH5017 at around 0155 GMT on Thursday, less than an hour after taking off for Algeria, following a request by the pilot to change course due to bad weather.
One of the two black boxes from the crashed Air Algerie flight has been sent to the Malian city of Gao for formal identification before being repatriated, French Foreign Minister Laurent Fabius has said.
A French contingent of troops is based in the city, which is a government-controlled town.
The Air Algerie AH5107 flight crashed in the northern Mali desert killing all 116 people on board.
The Gossi region where the accident occurred, near the Burkina Faso border, is 100 miles south of Gao.
French president Francois Hollande has said all avenues are being discussed after flight AH5017 crashed in the northern Mali desert, killing 116 people.
Nearly half of the passengers aboard the flight were French, many heading to Europe.
Speaking to reporters, Mr Hollande said that France will spare no efforts to find out what had happened.
"There are hypotheses, notably weather-related, but we don't rule out anything because we want to know what happened," the French president said.
Interior minister Bernard Cazeneuve added: "Terrorist groups are in the zone. ... We know these groups are hostile to Western interests."
A British man died onboard Air Algerie flight AH 5107, which crashed in the northern Malian desert killing least 116 people, the Foreign Office have said today.
– Foreign Office Spokesperson
It is with deep regret that the Foreign and Commonwealth Office confirms the death of a British man onboard Air Algerie flight AH 5107.

Air Algerie AH5017 crash investigators have said that it will be "very difficult to find all the bodies."
Speaking to reporters, General Gilbert Diendere, presidential aide and head of the crisis committee said:
– General Gilbert Diendere
There are French troops on site to secure a perimeter, to allow eventual investigators.
Concerning the bodies, you heard earlier (from the crisis committee meeting), it is very difficult because the bodies are scattered and I think it will be very, very difficult to find all the bodies.
All 118 passengers and crew were killed after the plane went down in the West African state of Mali.
The first images of the Air Algerie plane crash site in Mali show twisted metal and door panels lying in the sand.
French officials have said that they believed poor weather was the most likely cause of the crash in which 116 people died.
